Be it known that I, CHARLES C. citizen of the United States, residing in the city and county of San Francisco and State of California, have invented a certain new and useful Improvement in Loaf-Sugar- Packing Machines, of which the following is a specification.

My invention relates to machines for gathering and packing spaced loaf sugar, wherein horizontally reciprocating members and conveyers operate in conjunction with vertical movable means to superimposelayers of loaf sugar into receptacles; and the objects of my invention are First, to provide an improved machine for gathering and packing spaced loaf sugar;

Second, to provide an improved device of the character described wherein layers of loaf sugar are superimposed within a temporary packing receptacle; and

Third, to rovide an improved device wherein the ceding of the sugar will be automaticallydiscontinued when a predetermined number of layers have been superimposed within a receptacle. 7

I accom lish these several features by means of t e preferred form of the device disclosed in the drawings forming a part of the present specification wherein like characters of reference are used to designate similar parts throughout the said specification and drawings, and in which- Figure 1 is a broken side elevation of my improved machine.

whereby the power is disconnected from the machine when avpredetermined number of layers. of loaf sugar have been superimposed within the receptacle.

In the present state of the art loaf sugar is formed and laid upon trays spaced apart parallel converging runways formed by means of the angle'irons on walls 2. An endless conveyer 3 has its upper or working surface arranged flush with the table l and is connected with a superimposed iconveyer 4 by means of suitable gears 6 and 7, the gear 7 being slightly smaller than the gear, 6, in order to move a distance equal to a certain. number of sugar loaves 9 and the spaces between them, while the conve er 3 1s movmg a distance equalto the same number of loaves only, the purpose of which will hereinafter be more fully described.

Flights 8 on the conveyer 4 are used to move the loaves.

. The conveyer 3 is providedwith a ratchet wheel 12 which is rotated intermittently by,

means of a pawl 14 pivotally mounted upon an arm 15 in turn rotatably mounted upon the shaft 11 of the conveyer-'3.

'A connecting rod 16 o eratively connects the arm 15 and pawl14 t ereon with a horizontally reciprocating feeding member 18 longitudinal grooves 19 within the frame or table An oscillating lever 21 is operatively connected at its upper end with the reciprocatingior-feeding member 18 while the lower on portion of the frame 1 as at 22.-

The lever 21'is oscillated, with a rest period, by means of two diametrically opposed cam 23 mounted upon the shaft24c o 27 mounted uponthe drive shaft 28.

of said lever is fulcrumed to the lower slight a gear 26 in mesh with adriving gear;

One end of the drive shaft 28 is provided with a disk 29 having a recess 31; within ,which ispivotally mounted a pawl 32. The

of operative awl P at 32 1s normallgohliilil outf no I . 'ably within a disk 38 by means of a small wheel or roller 33 rotatably mounted upon a releasing member or lever 34-. r

A suitable spring 36 serves to move the pawl 32 into the recess 37 when the roller 33 is removed, thereby causingthe disk 38 secured to a power pulley or sheave 41 to engage the pawl 32 and rotate the power shaft 28 through one revolution. As the pawl 32 is rotated and approaches its former position time been returned'to the position disclosed in Fig. 7 of the drawings, diseng ges the said pawl 32 from the recess 3 of the disk 38 and as a table 43 is lowered a predetermined number of steps for each revolution of the disk 29, the power is thus automatically removed from the machine when a certain number of layers of loaf sugar have been superimposed within the receptacle 42 member or frame 43.

The receptacles 42 are arranged opposite the ends of the runways on the surface of the table 1. i

The vertically movable'member 43 is slidmounted in suitable grooves 44 within v the side walls of the frame or table 1 and 64 and into the path of the is provided with ratchet teeth 46.

A cord 47 is secured near the lower portion of the movable member 43 and after passing over a suitable pulley 48 supports a weight 49 whereby the movable member 43 is normally elevated. A pawl 51 normally prevents the elevation of the movable memer which is intermittently lowered to permit successive layers of loaf sugar to be superimposed wit in the receptacle or container 42 by means of a pawl 52 mounted upon an arm 53 in turn operated by diametrically opposed cams 54 secured to the shaft of a gear 56 in mesh with the main driving gear 27 on the main drive shaft 28.

The reciprocating member 18 is rovided on each side thereof with camp ates 17 which extend'beyond the sides of'the frame 1 and are arranged to engage the rollers 57 on the sides of a frame or yoke 58 pivotally mounted as'at 59 upon the outer walls 2 of the runways. a

The yoke 58 has a depending portion 61 extending into the receptacle 42 and provided with a resilient cushion 62, the purpose of which will hereinafter be more fully described.

'A second yoke 64 is also pivotally mounted as at 59 and is provided with opposed pins 66 extending outwardly from said yoke oke 58 below it. The yoke 58 is also provided with a depending portion 67 having a cushion 68,

the purpose of which will hereinafter be more fully set forth.

By referring to Fig. 1 of the drawings it will be noted that the rotat o of the gear the roller 33, which has mean-- upon a vertically movable naeegira 27 will operate the gears 26 and 56, which have a ratio of two and onehalf to one relatively to the gear 27, and as both gears 26 and 56 are provided with two diametrically opposed earns 23 and 5 4 respectively so that the levers 21 and 53 are operated five'times during each revolution of the gear 27 which is the number in the present instance, of the superimposed layers of loaf sugar within the container or receptacle 42.

By again referring to Fig.1 of the drawings, it-will'be noted that as the gear 26 is rotating in the direction indicated by the curved arrow the cam 54 will operate the lever or arm 53 to lower the movable memher 43 one space while the uppermost cam 23 is traversing the rest period represented i or pulley 41. This will rotate the main drive shaft 28 and gear 27 thereon by means of which the gear 26 and cams 23 will operate to oscillate the lever 21 and thereby reciprocate the horizontally reciprocating member 18. This reciprocating movement will be imparted to the connecting rod 1.6 to intermittently operate the pawl 14 and ratchetv wheel 12 of the conveyer 3. By means of the gears 6 and (the conveyor 4 is operatedand the flights 8 thereon operate to gather longitudinally the spaced apart loaf sugar 9 on a tray 10, which has been inserted into the machine with loaves thereon spaced in both directions. The flights 8, as they are operated intermittently by the reciprocating movement of the member 18, move the longitudinally gathered loaves of sugar 9 into the converging ends of the -,runways formed by the walls or angle irons its ire

veying them into the rece tacle until .the

bottom of said receptacle is ed.

While the layer of loaf sugar is being fed into the receptacle 425 said layer passes under the cushion 68 of the yoke 64 and the cushion 62 of the yoke 58 said yokes having been raised by t e cam plates 17 on the forward movement of the member 18. As.

the loaves of sugar 9 drop ofi from the end of the table 1 onto the member 18 they are nasal '15 by the end of said table 1 and thereby prevented from returning with said member 18. As the member 18 nears the end of the return stroke the yoke 58 is lowered and the cushion 62 thereon engages. and breaks apart the loaves of the continuous layer which may have been caused to stick together by the pressure of the 'conveyer 3' which intermittently feeds .the said layer into the receptacle 42.

When one cam 23 has released the lever 21 there is'ashort rest period'before the opposite cam- 23 again engages the lever for the next. forward movement into the receptacle 42, which rest period is-represented by the space between the upper cam 23 and the lever 21 as disclosed in Fig. 1 of the drawings. During this rest period and while the member 18 is withdrawn from the receptacle 42, one of the cams 54 operates the lever 53 and pawl 52 thereon to.

the loaf sugar forward is automatically stopped. Before the roller 33 is again moved to operate the machine the pawls' 51 perand 52 are released from the rack 46 to mitthe weight 49 to raise said table 43, and the receptacle 42 thereon, to its uppermost position.

The filled receptacles are then removed and replaced by empty ones and the roller 33 again moved to release the pawl 32 to again operate the machine as hereinbefore described. I
